Improved car-coupling



To all whom it, may co'ncern phia, in the county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement 1 in Oar-Coupling and I do hereby declare that the fol- :lowingis a full and exact vdescription 'of the same, reference being had: to the accompanyingr drawings, and

to the letters of reference marked thereon.

which is automatic in their action; .and consists mainly in the combination of a revolving keeper' in the lower part of the `draw-head, with a swinging keeper in the upper part, by means of which `the link is securely held.

`struction and operation. l

` A represents the draw-head of a car, which is profice c. l

B represents a shaft,which its into the orifice a', Aand turns freely therein. Upon this. shaftis located the keeper O, as shown in igs. 1 and 2.

D represents a swinging keeper', which is pivoted in the upper part of the draw-head, the motion of which, however, is limited to the lperpendicular line x, as shown.

E represents a slide, which, when in position, is located' behind the keeper D, for the purpose of preventing it 'from being accidentally thrown upward.

i F represents a pocket, in which the slide E is placed when'not needed for use.

Grepresents the link, which is preferably constructed of steel, and made thin' in the centre, in orderto permit the necessary play incidental to the vibration of y the cars. If desired, itmay be constructed of a steel ll OSEPEDUN OTT, OE PHILADELPHIA, PEN N SYLVANI v SELE AND GEORGE GIBSON, OF SAME ne in known that I, JOSEPH DUNOTT, of Phi-ladet- This invention relates to that class of car-couplingsv It further consists, also, in certainv details of cou-y. struction, which, in connection with the foregoing, will luy-invention, 'I will nowproceed to describe `its convided lwith the longitudinall slot a, and transverse o ri-` IMPRQVED csa-c:ernannte.l

band, and strengthened with iron plates about the To the shaft B is attached a lever, which rises above the platform to any point convenient for operating it. It is ordinarily secured in place by a spring-catch or other similar device.`

The foregoing description relates to the draw-head which is used for uncoupling. The other draw-head of the pair is constrnctedin all points like this, excepting that the sli-aft B is omitted, and a projection siniilar to the pait of the`keeper c, exposed above the lower surface of the draw-head A, is 'cast uponl the corresponding part of the draw-head fflhe operation is as follows:

@The link ordinarily remains securely held in drawhead H. As the cars come together, its free end enters draW-headA, strikes upon the inclined side of' the keeper O, swings back the keeper D, and, falling behind the keeper O, is securely fastened in this position by the keeper D, which swings back into place' by its own weight. 41f it is desired to Vlock itin ,thisposition, the slide F is placed in the proper orifice,`

when it becomes impossible for-the cars to become accidentally uncoupled.

When it is desired to unconple the cars, however, the lever' attached to the shaft is disconnected from ihespring-c'atch' by which it is held, and thrown forward. By this operation, the keeper() is moved belowthe line of the draw-head, and the link isfree `to come out.

By the construction herein described, an extremely simple and eiiicient coupling is produced.
